What can affect soil?
Soils are formed through the interaction of five major factors: time, climate, parent material, topography and relief, and organisms. The relative influence of each factor varies from place to place, but the combination of all five factors normally determines the kind of soil developing in any given place.
What causes poor soil?
Poor soil quality can result from inadequate fertilisation, infrequent crop rotation or over farming of the same land. A reduction in soil quality can also result from both water shortages and excessive rain. … Flooding and precipitation leaches nutrients out of the soil, and often erodes the top layer of soil itself.
What causes barren land?
Deforestation, overgrazing and mining, all are equally responsible for an increase in the rate of erosion by water. … Soil erosion due to water is the most serious land degradation problem in India. It causes land degradation through huge loss of top fertile soil along with plant nutrients through runoff water.
What is African soil?

Why is Africa always starving?
In general, the principal causes of hunger include poverty, conflict, climate and weather, lack of investment in agriculture, and unstable markets. (World Food Programme, 2018).

Poor drainage is often a factor in sodic and salinic soils. If this is the case in your garden, you can improve the soil by incorporating compost, sand or pea gravel (see No. 2 above). Pond fresh water on the area to leach sodium out of the soil and away from the plants’ root zone.
Is dark soil fertile?
